- The problem is that this request isn't being sent to the remote machine.
- Your machine has the file cached in memory. Therefore, it's making the
- access decision locally.
-
- I think Sun has a patch for this. Since it's security-related, it may even
- be in the UUNET patch archive.
-
- This doesn't explain why you were having the opposite problem, though. In
- that case, the file shouldn't be cached, so when you try to access it as
- yourself your system should try the NFS request again.
